New Guinea Impatiens plant named ‘Duemagdarre’

ABSTRACT

A new and distinct cultivar of  Impatiens  plant named ‘Duemagdarre’ characterized by its upright, outwardly spreading and mounding plant habit; freely branching habit; vigorous growth habit; dark green-colored leaves; freely and early flowering habit; large red-colored flowers; and good garden performance.

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DUEMAGDARRE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of NewGuinea Impatiens plant, botanically known as Impatiens hawkeri andhereinafter referred to by the name ‘Duemagdarre’.

The new Impatiens plant is a product of a planned breeding programconducted by the Inventor in Rheinberg, Germany. The objective of thebreeding program is to create new vigorous and uniform New GuineaImpatiens plants with large attractive flowers.

The new Impatiens plant originated from a cross-pollination made by theInventor in July, 2008 in Rheinberg, Germany of a proprietary selectionof Impatiens hawkeri identified as code number F-16-1021, not patented,as the female, or seed, parent with a proprietary selection of Impatienshawkeri identified as code number F-19-0418, not patented, as the male,or pollen, parent. The new Impatiens plant was discovered and selectedby the Inventor as a single flowering plant from within the progeny ofthe stated cross-pollination in a controlled greenhouse environment inRheinberg, Germany in May, 2012.

Asexual reproduction of the new Impatiens plant by terminal cuttings ina controlled greenhouse environment in Rheinberg, Germany since June,2012 has shown that the unique features of this new Impatiens plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Impatiens have not been observed under all possibleenvironmental conditions and cultural practices. The phenotype may varysomewhat with variations in environmental conditions such astemperature, daylight and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duemagdarre’. These characteristics incombination distinguish ‘Duemagdarre’ as a new and distinct Impatiensplant:

-   -   1. Upright, outwardly spreading and mounding plant habit.    -   2. Freely branching habit.    -   3. Vigorous growth habit.    -   4. Dark green-colored leaves.    -   5. Freely and early flowering habit.    -   6. Large red-colored flowers.    -   7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the femaleparent selection. Plants of the new Impatiens differ primarily fromplants of the female parent selection in growth habit as plants of thenew Impatiens are more vigorous than plants of the female parentselection. In addition, plants of the new Impatiens have larger flowersthan plants of the female parent selection.

Plants of the new Impatiens can be compared to plants of the male parentselection. Plants of the new Impatiens differ primarily from plants ofthe male parent selection in flower color as plants of the male parentselection have lighter red-colored flowers. In addition, plants of thenew Impatiens are more freely branching than plants of the male parentselection.

Plants of the new Impatiens can be compared to plants of Impatienshawkeri ‘Kitenan’, not patented. In side-by-side comparisons conductedin Rheinberg, Germany, plants of the new Impatiens differed primarilyfrom plants of ‘Kitenan’ in the following characteristics:

-   -   1. Plants of the new Impatiens were more vigorous than plants of        ‘Kitenan’.    -   2. Plants of the new Impatiens had larger leaves than plants of        ‘Kitenan’.    -   3. Plants of the new Impatiens were more freely flowering than        plants of ‘Kitenan’.    -   4. Plants of the new Impatiens had larger flowers than plants of        ‘Kitenan’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Impatiens plant showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photograph may differ slightly from the color values citedin the detailed botanical description which accurately describe thecolors of the new Impatiens plant.

The photograph comprises a side perspective view of a typical floweringplant of ‘Duemagdarre’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown during the summer in 10.5-cm containersin a glass-covered greenhouse in Rheinberg, Germany and under culturalpractices typical of commercial New Guinea Impatiens production. Duringthe production of the plants, night temperatures averaged 18° C. andlight levels averaged 4,500 lux. Plants were pinched one time threeweeks after planting and were 16 weeks old when the photograph anddescription were taken. In the following description, color referencesare made to The Royal Horticultural Society Colour Chart, 1995 Edition,except where general terms of ordinary dictionary significance are used.
